In 2008 Tesla motors delivered 150 of its critically acclaimed Roadsters. Even in the harsh economic conditions they plan on ramping up production in 2009. They plan to increase the rate of production from 15 to 30 cars per week later in the year.

Tesla will display their cars at an auto show for the first time at the North American International Auto Show.

They submitted loan applications for up to $400 million dollars in federal loans for their Model S car and to expand powertrain production.

After taking their roadshows to 5 cities in 2008 to allow drivers a chance to test the roadster, there are plans to expand the schedule in 2009.

Tesla received a infusion of $40 million in convertible debt financing from its investors this week. The board approved the cash to speed up the manufacturing process of the Tesla Roadster.

“Forty million is significantly more than we need,” said Elon Musk, Tesla Chairman and CEO. He goes on to say “However, the board, investors and I felt it was important to have significant cash reserves.”

Not only will the money help with production, but they will also use the cash to expand Tesla’s electric powertrain supply business and future product development. Tesla, like every other car maker, has recently had some issues due to the economic downturn and credit crunch, but demand for their cars is still high.

Tesla may have had some setbacks lately with the faltering economy, but they are pressing forward with their much anticipated 4 door model. The Tesla S (S for sedan) is now set to be released in 2011, and the company has started releasing teaser photos onto the Internet.

The new 4 door sedan is expected to have an impressive 240 mile all electric range with a 0 to 60 time of under 6 seconds. The price tag is set at $60,000.

Tesla’s planned S sedan that we wrote about last month looks like it might be delayed 6 months. The horrible economic downturn is causing Tesla to go into capital preservation mode which includes possible layoffs and delays. The company was relying taxpayer backed loans to cover most of the development costs, and with those loans rapidly drying up, they may have to go to plan B for the “S” sedan.

Tesla still expects to make 15,000 sedans a year by the end of 2011. The US Dept. of Energy has approved a loan of $150 billion to Tesla which appears to still be on track. The 5 passenger sedan is expected to have a $60,000 price tag, much lower than the $110,000 Tesla Roadster.

Tesla is set to make a big splash with its introduction of a second car to their lineup - the Model S sedan. The plug in electric model will run on lithium-ion batteries and is said to have a range of 240 miles. If its anything like the critically acclaimed Roadster, it should have plenty of power. Arriving in late 2010, the sedan is set to have a price tag of $60,000, which is significantly cheaper than the Roadster.

An interesting look at the all electric Telsa Roadster as driven by their first official customer - Jay Leno. The groudbreaking technology and performance of this car should quickly filter down to more affordable applications for the everyday consumer.
